In the mime ACL:
deny
condition = ${if match {$mime_filename}\
{\N\.(com|vbs|bat|pif|scr|exe)$\N}}
message = no Windows executeables accepted here
log_message = reject, ${substr_-4_4:$mime_filename} file

If you're using clamav, you can simply drop the demime from those
stanzas; clamav has been able to scan within mime attachments for quite
some time. If you're using a different virus scanner that cannot scan
within mime attachments on its own, you'll probably need to do something
with the decode modifier in the MIME acl, but as I use clavav, I'm not
sure what the exact syntax is.
